Frequently Asked Questions
Does the X-MAS use standard guardrail posts?
All the posts are steel. The first two posts are special, all other posts are
standard steel guardrail posts.
CAN the X-MAS be installed without a foundation?
The X-MAS is designed to be installed in-ground using standard guardrail
installation equipment..
IS A TRANSITION NEEDED TO ATTACH TO STANDARD DOUBLE
SIDED GUARDRAIL?
The X-MAS is designed to attach directly to standard double faced
guardrail with no transition required.
can the x-mas be installed using composite blockouts?
The x-mas can be ordered with either wood or composite blockouts.
CAN the X-MAS BE ATTACHED TO CONCRETE BARRIER?
The X-MAS can be attached to concrete barrier with the addition of
standard transitions..
IS THE X-MAS REUSABLE AFTER A DESIGN IMPACT?
The X-MAS is designed to be a sacrificial crash cushion, making it ideal
for low impact locations.
DISTRIBUTED BY:
The X-MAS is available with an optional high
visibility nose.
